Sponges absorb a high amount of liquids.
What do you think methane is if it isn't a chemical? The easiest way to get methane in a laboratory is to open the natural gas tap, since natural gas is mainly methane.

Yes, although you'll need special equipment depending on what you'd like to prepare the uranium for. - in a nuclear physics laboratory artificial uranium isotopes can be obtained - if you think to the preparation of uranium (as a metal) from other compounds this is very possible but not in a simple laboratory - uranium has 3 natural isotopes
The concentration; to prepare a solution the compound must have a solubility.

You have to ensure there is good ventilation when you prepare chlorine in a laboratory because chlorine is toxic so you need to ventilate it to avoid breathing it in.
You can prepare 13-dibromopropane in the laboratory from lower alkanes or alkyl halides using HBr in the presence of peroxide.

Yes, they did. Laboratory experiments showed them the results.

We cant prepare it in lab. But there are aquas ammoni in lab.
